Abstract: The production of a physiologically active substance by a normal, transfected or transformed cultured cell can be increased by culturing the cell in a culture medium containing cobalt and molybdenum. The culture medium is one ordinarily selected for growing those types of cells which produce a desired, physiologically active substance, e.g., a recombinant growth factor of a monoclonal antibody. When cobalt and molybdenum are included in any of these growth media, a substantial improvement in the production of a physiologically active substance by the cells can be observed.      Compositions and methods utilizing cobalt and molybdenum as additives for culture media are described.

Title: Fast acquisition of traffic channels for a highly variable data rate
Inventor: PROCTOR JAMES A JR
IPC: H04J13/18
Filed: 1999-05-26
Abstract: A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a given long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physical connections between the subscriber units and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber units are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronism. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels. Preferably, the code phases of the new channels are assigned according to a predetermined code phase relationship with respect to the code phase of the corresponding maintenance subchannel.

Title: Method and apparatus for frac/gravel packs
Inventor: HAILEY TRAVIS THOMAS SR
IPC: E21B43/10
Filed: 2001-03-06
Abstract: A method and apparatus for fracturing a formation or gravel packing a borehole extending through an unconsolidated subterranean zone in a formation includes a screen assembly having a length adapted for disposal adjacent the unconsolidated subterranean zone and includes a plurality of screens mounted on a base member with adjacent base members being connected by a sub having an aperture in the wall thereof. A flow-control service assembly is disposed within the bore of the screen assembly and includes an outer tubular member and an inner tubular member. The outer tubular member includes a plurality of ports that communicate with the apertures in the screen assembly. The apertures in the screen assembly are disposed along the length of screen assembly at predetermined intervals. The inner tubular member and outer tubular member form an inner annulus, the outer tubular member and screen assembly form a medial annulus, and the screen assembly forms an outer annulus with the wall of the borehole. Barriers are placed around the ports on the outer tubular member to prevent the formation of gravel bridges across the inner annulus.  The inner annulus provides alternative flow paths around the ports upon the ports becoming closed to fluid flow such as by bridges. In operation, fluids, such as fracing fluids or a gravel slurry, is pumped down the inner annulus, through the ports in the outer tubular member and apertures in the screen assembly and into the outer annulus prior to passing through the perforations into the formation. Return fluid may pass through the screens, through the medial annulus and into the flowbore of the inner tubular member to flow to the surface. The fluid flowing through the inner annulus passes through the ports and apertures into the outer annulus substantially uniformly along the length of the screen assembly thereby creating fractures uniformly along the unconsolidated subterranean zone from top to bottom.

Patent CA-2352990-A1 (CA)
Inventor: GRAVES ALAN F
IPC: H04Q11/04
Filed: 2001-07-13
Abstract: A communications signal which carries a purely digital wrapper signal and a method and system for generating it and extracting overhead information therefrom. The wrapper signal can be received by a high-performance format-specific receiver at the end of the network as part of the overall payload, but can also be detected by a low-bandwidth payload-bit-rate-insensitive receiver at an intermediate node. This is achieved by using alternating payload and wrapper segments and providing special digital coding on the wrapper segments.      Specifically, each wrapper segment consists of a contiguity of signal level sequences, each of which is a multi-bit symbol that encodes a bit in the overhead bit stream. Each of the symbols is thus a signal level sequence having one of two possible transition patterns, with the appropriate symbol being chosen depending on whether the overhead bit is a logic " zero" or a logic "one" . The two symbol patterns which represent logic "zero" and logic "one" each contain enough transitions to meet synchronization and automatic gain control requirements associated with various network equipment, while containing a sufficiently distinct average signal level (or pulse density) to allow a receiver to associate the resultant short-term D.C. offset with the correct wrapper symbol.

Title: System and method for authentication of network users with preprocessing
Inventor: WILDER JONE
IPC: G06F1/00
Filed: 1999-05-20
Abstract: A network authentication system provides verification of the identity or other attributes of a network user to conduct a transaction (14-50), access data or avail themselves of other resources. The user is presented with a hierarchy of queries based on wallet-type (basic identification) and non-wallet type (more private) information designed to ensure the identity of the user and prevent fraud, false negatives and other undesirable results (52-72). A preprocessing stage is employed to ensure correct formatting of the input information and clean up routine mistakes (such as missing digits, typos, etc.) that might otherwise halt the transaction. The authenticator can be configured to require differing levels of input or award differing levels of authentication according to security criteria (14-50).
